--- fixes: - When we pass a workflow environment to workflow parameters using 'env' Mistral first evaluates it assuming that it can contain expressions (YAQL/Jinja) For example, one environment variable can be expressed through the other. In some cases it causes problems. For example, if the environment is too big and has many expressions, especially something like <% $ %> or <% env() %>. Also, in some cases we don't want any evaluations to happen if we want to have some informative text in the environment containing expressions. In order to address that the 'evaluate_env' workflow parameter was added, defaulting to True for backwards compatibility. If it's set to False then it disables evaluation of expressions in the environment.
